The life of quench oil is dependent upon its thermal stability. The thermal stability is a function of the quality of the base oil, the antioxidant package used, and the presence of heat and catalysts. In this paper, the mechanism of quench oil degradation and the function of antioxidants will be explained. Copyright © 2013 ASM International®. All rights reserved.

Non-Ferrous rolling lubricants have traditionally been designed from a common platform of chemistries. Historically this chemical platform has produced properties that compromise some of the intended performance aspects. This presentation will review the historical perspective of Non-Ferrous rolling oils, as well as offer some insight into positive attributes that new chemistries have delivered. By making use of chemical technology, next generation rolling lubricants can be developed that provide improvements in emulsion consistency, improvements in lubrication properties and performance, and improvements to metal surface finishes.

The effect of quench rate on the natural aging behavior was examined using microhardness, conductivity and the differential scanning calorimeter. The data indicated that GPZ formed during extended natural aging of 7075, while extended aging of 7050 resulted in the precipitation of η'.

An induction hardening operation heat treating engine valves previously used a typical medium speed quenching oil for the quenchant. A change-over to vegetable-based oil was accomplished, with the goal of reducing fire hazards; reducing smoke and fumes; and providing a cleaner working environment. All the desired goals were achieved, with additional advantages of no changes in microstructure, and improved part distortion. This paper compares the physical properties of the two oils, and documents improvements in working environment. © 2015 ASM International®.
